It is machined from 300x100x20 slab of aluminium. There is provision for both Super Silencer mounting and tuned pipes (test stand can also be used for F2A tests). 

The stand will be bolted down to a Workmate with 4 off 6mm cap heads.

A good test stand is the starting point for repeatable engine testing.

The parts are being made according to the excellent article that Peter Halman wrote in Aeromodeller  issue 1035

Back issue 1035 link

The Super Silencers are part way through manufacture, I am making a few for my friends as well, the turbo cone plug head are done and all of the fixtures for modifying the cylinder porting on the milling machine are manufactured and ready for use.

Nice workmanship there.

I think there are great possibilities for both composite tanks and the 3D printed tanks that we have been trialling this year.

 We have won competitions using the 3D printed tanks, in the case of the tank shown above it enables the fuel head to be optimally placed for that type of model.
